尝试使用gwt-cal和gwt-dnd时出错

Question

我有一个简单的GWT项目,我试图使用gwt-cal小部件,但是当我尝试加载我使用小部件的页面时,我收到错误.

我按照这里的说明使用gwt-cal小部件,但它不起作用.我有gwt-cal的0.9.3版本,gwt-dnd的版本3.1.2,我正在使用GWT 2.4.

这是我使用gwt-cal小部件的页面:

public class ClientCalendarPage extends Composite {

private VerticalPanel mainPanel = new VerticalPanel();
private Calendar calendar;

public ClientCalendarPage() {
    CalendarSettings settings = new CalendarSettings();
    settings.setEnableDragDropCreation(false);
    settings.setEnableDragDrop(false);

    calendar = new Calendar();
    calendar.setSettings(settings);
    calendar.setDate(new Date()); // calendar date, not required
    calendar.setDays(3); // number of days displayed at a time, not required
    calendar.setWidth("500px");
    calendar.setHeight("400px");

    Appointment appt = new Appointment();
    appt.setStart(new Date(System.currentTimeMillis() + 86400000));
    appt.setEnd(new Date(System.currentTimeMillis() + 90000000));
    appt.setTitle("Test");
    appt.setStyle(AppointmentStyle.BLUE);
    calendar.addAppointment(appt);

    mainPanel.add(calendar);

    initWidget(mainPanel);
}
 }

这是我的app.gwt.xml:

<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='minoscrossfit'>
 <inherits name='com.google.gwt.user.User'/>
 <inherits name='com.google.gwt.user.theme.clean.Clean'/>                                   
 <inherits name='com.bradrydzewski.gwt.calendar.Calendar' />
 <inherits name='com.bradrydzewski.gwt.calendar.theme.google.Google' />
 <inherits name='com.allen_sauer.gwt.dnd.gwt-dnd'/>
 <entry-point class='com.afrsoftware.minoscrossfit.client.MinosCrossfit'/>
 <source path='client'/>
 <source path='shared'/>
</module>

最后,这是我得到的堆栈跟踪:

任何人都可以看到我做错了什么？

我发现了这个问题.我在项目中缺少一些语言环境.我改变了我的app.gwt.xml并且它有效.我用这里的文档来解决这个问题.

这是我的app.gwt.xml现在的样子:

<?xml version="1.0" encoding="UTF-8"?>
 <module rename-to='minoscrossfit'>
  <inherits name='com.google.gwt.user.User'/>
  <inherits name="com.google.gwt.i18n.I18N"/>
  <extend-property name="locale" values="fr"/>
  <extend-property name="locale" values="fr_CA"/>
  <extend-property name="locale" values="en"/>
  <inherits name='com.google.gwt.user.theme.clean.Clean'/>                                     
  <inherits name='com.bradrydzewski.gwt.calendar.Calendar' />
  <inherits name='com.bradrydzewski.gwt.calendar.theme.google.Google' />
  <inherits name='com.allen_sauer.gwt.dnd.gwt-dnd'/>
  <entry-point class='com.afrsoftware.minoscrossfit.client.MinosCrossfit'/>
  <source path='client'/>
  <source path='shared'/>
 </module>

一个小项目 - >日食中的清洁似乎有助于解决我的问题.

我改变了app.gwt.xml之后添加了类似的问题,这是因为有人在我的球队(可能是我)已承诺是不应该被提交(在nocache.js),所以在项目中使用的新罐子文件不属于这个文件.更改app.gwt.xml挑起了应用程序的重新编译和新nocache.js文件(从罐子所有需要的功能)的产生.
